    1990 larson 21' All American with cuddy (opinion please!!)

    I would like to buy a boat for our young family of four for tubing and skiing. We would routinely have another family with us on the water. A cuddy would be nice to get the kids out of the weather (we have had some bad trips where it started raining). We live on an amazing deep water river...
